Background informationPolyadenylation of mRNA precursors is a two-step reaction that requires multiple protein factors. The first step, endonucleolytic cleavage of polyadenylation substrates, requires CstF (cleavage stimulation factor), a heterotrimer that is composed of three distinct subunits. CstF-64 contains an RNA binding domain and is responsible for the RNA binding activity of CstF. CstF-64 is expressed in all somatic cells and in pre- and postmeiotic, but not meiotic, germ cells. However, a large variant of CstF-64, called t CstF-64, is abundantly expressed in meiotic and postmeiotic cells in the testis and to a lesser extent in the brain, and promotes the germ cell pattern of polyadenylation. The gene encoding CstF-64 (designated CSTF2) maps to the X chromosome, whereas t CstF-64 is encoded by an autosomal gene. The increase in CstF-64 concentration during B cell activation switches IgM heavy chain mRNA expression from membrane-bound to secreted forms, suggesting that CstF-64 plays a key role in regulating IgM heavy chain expression during B cell differentiation.

AdvisoryAvoid freeze/thaw cycles as they may denaturate the polypeptide chains of the antibody, thus reducing its reactivity, specificity and sensitivity. For antibodies that are in liquid form or reconstituted lyophilized antibodies small amounts could become entrapped on the seal or the walls of the tube. Prior to use briefly centrifuge the vial to gather all the solution on the bottom.
PropertiesFor facs or microscopy Alexa 1 conjugate.
ConjugationAlexa Fluor,ALEXA FLUOR® 594

DescriptionThis antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.
GroupPolyclonals and antibodies
AboutPolyclonals can be used for Western blot, immunohistochemistry on frozen slices or parrafin fixed tissues. The advantage is that there are more epitopes available in a polyclonal antiserum to detect the proteins than in monoclonal sera.
